a. 43 CS
b. 36 CS
c. 20 CS
d. 0.065 CS - ✔️✔️A. Cs = Vt/(Pplat - PeeP) Cs = 725 / (27-10), Cs=725/17,
42.64=725/17
2. Air accidently trapped in the lungs due to mechanical ventilation is known as which of
the following?
a. Plateau pressure (Pplateau)
b. Functional residual capacity (FRC)
c. Extrinsic positive end expiratory pressure (extrinsic PEEP)
d. Intrinsic positive end expiratory pressure (intrinsic PEEP) - ✔️✔️D Intrinsic positive
end expiratory pressure (intrinsic PEEP) aka auto-peep
3. How many variables can a ventilator control at one time?
a. One
b. Two
c. Three
d. Four - ✔️✔️A One
4. The pressure required to maintain alveolar inflation is known as which of the
following?
a. Transairway pressure (PTA )
b. Transthoracic pressure (PTT)
c. Transrespiratory pressure (PTR)
d. Transpulmonary pressure (PL) - ✔️✔️d. Transpulmonary pressure (PL)
5. The term used to describe the tendency of a structure to return to its original form
after being stretched or acted on by an outside force is which of the following?
a. Elastance
b. Compliance
c. Viscous resistance
d. Distending pressure - ✔️✔️A Elastance
, 6. The condition that causes pulmonary compliance to increase is which of the
following?
a. Asthma
b. Kyphoscoliosis
c. Emphysema
d. Acute respiratory distress syndrome (ARDS) - ✔️✔️C Emphysema
7. Use this figure to compute the static compliance (CS) for an intubated patient with an
exhaled tidal volume (VT) of 500 mL.
a. 14 mL/cm H2O
b. 20 mL/cm H2O
c. 33 mL/cm H2O
d. 50 mL/cm H2O - ✔️✔️D 50mL/cn H2O
8. The ventilator that functions most physiologically uses which of the following?
a. Open loop
b. Double circuit
c. Positive pressure
d. Negative pressure - ✔️✔️D Negative pressure
9. Plateau pressure (Pplateau) is measured during which phase of the ventilatory cycle?
a. Inspiration
b. End-inspiration
c. Expiration
d. End-expiration - ✔️✔️B End-inspiration
10. Calculate airway resistance (Raw) for a ventilator patient, in cm H2O/L/sec, with the
following information: Peak inspiratory pressure (PIP) is 20 cm H2O, plateau pressure
(Pplateau) is 15 cm H2O, PEEP is 5 cm H2O, and set flow rate is 50 L/min.
a. 5 Raw
b. 6 Raw
c. 10 Raw
d. 15 Raw - ✔️✔️B 6 Raw
Raw = (PIP - Pplateau)/flow
Remember to convert 50L/min to seconds, so 50/60 = .833 and 5 / .833 = 6.02
11. The body's mechanism for conducting air in and out of the lungs is known as which
of the following? - ✔️✔️Spontaneous ventilation
12. Which of the following are involved in external respiration? - ✔️✔️Alveoli and
pulmonary capillaries
